Phase composition of melt-quenched carbon doped tungsten silicides

详细

The phase transformations in carbon doped tungsten silicides are studied. In the eutectic alloys of tungsten silicides depending on the level of doping with carbon, SiC is present in the structure immediately after quenching or only after additional annealing (aging). The effect of the silicon content in the alloy on the type of formed carbides is detected. The possible features of the W–Si–C phase diagram are discussed.
